A rectangle’s length is represented by the expression (3x + 9). The width is represented by the expression (2x – 5). Which expression represents the perimeter of the rectangle?
A.
5x + 4

B.
5x + 14

C.
10x + 8

D.
10x + 13

Answer:

x=number of hours

c(x)= 25x+75

y-intercept= (0, 75)

Equation= y=25x+75

Slope= 25

Step-by-step explanation:

75 would be the y intercept(constant) because that's the initial charge for a call.

25 would be the coefficient for x because the hour you spend on the call varies.

The slope is how steep the line is, in this case it is 25.

x is the number of hours because that is the time that varies.

Answer:

192ft squared. But remember it says don't put the square feet so just type in: 192.

Step-by-step explanation:

The top triangle is 42 ft squared.

The rectangle below it is 150 feet squared.

You add them together and get 192 ft squared hope this helps!

The number of employees Sasha would need next weekend are = 46

For a weekend, 15 employees = 390 wardrobes

The number of wardrobes to be assembled next weekend= 1200

If 390 wardrobes = 15 employees

1200 wardrobes = X employees

Make x the subject of formula,

X = 1200 × 15/390

X = 18000/390

X = 46

Therefore, the number of employees Sasha would need next weekend are = 46

Answer:

(4, 4)

Step-by-step explanation:

So you're trying to find what P' is, and P' would be the dilation of P. This means that you apply the rule (x, y) --> (1/4x, 1/4y) with the coordinate point (16, 16). This would be:

(16, 16) --> (1/4 * 16, 1/4 * 16) = (4, 4)

Answer:

989.6inches^2

Step-by-step explanation:

A) Radius = You half the diameter so... 21/2

Radius = 10.5

Height = 15

A = 2 x pi x d/2 x h

B) 2 x pi x 21/2 x 15

A = 989.6inches^2

Answer:

(b) 60.21ft^2

Step-by-step explanation:

Given

The attached triangle

Required

Number of square feet materials needed

This simply means that we calculate area;

[tex]Area = 0.5 * base * height[/tex]

[tex]Area = 0.5 * (14ft\ 2in) * (8ft\ 6in)[/tex]

Convert to ft [divide by 12]

[tex]Area = 0.5 * (14+ 2/12) * (8+ 6/12)[/tex]

[tex]Area = 0.5 * (14.17) * (8.5)[/tex]

[tex]Area = 60.23ft^2[/tex]

Answer:

420 ft^2

Step-by-step explanation:

[tex]h = \sqrt{25 ^{2} - 7 } [/tex]

[tex] = \sqrt{570} [/tex]

[tex] = 24[/tex]

[tex]a = \frac{1}{2} (b1 + b2)h[/tex]

[tex] = \frac{1}{2} (14 + 21)(24)[/tex]

[tex]answer = 420ft ^{2} [/tex]

Answer:

245 ft sq

Step-by-step explanation:

Find the are of the triangle and the square seperatly.

Area of a square is A = s * s

A = 14  * 14 = 196 ft sq

Focusing on the triangle, the dotted line is the same length as the bottom of the square. 14 ft

Area of a triangle is A = 1/2 * b * h

A = 1/2 * 14 * 7

A = 7 * 7

A = 49 ft sq

So, 196 + 49 = 245

[tex]\theta \approx 1.23^\circ[/tex]

Step-by-step explanation:

The expression has been given as:

[tex]tan(\theta) = \frac{50}{18}[/tex]

Required: Find [tex]\theta[/tex]

Simplify the fraction

[tex]tan(\theta) = 2.7778[/tex]

Take arc tan of both sides

Density" of the given granite block is 2.7g/cm

.

Explanation:

Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=

v

m

where, “m" mass of an object and "v" is volume of an object.

Given that,

Dimensions of the block are 20 cm, 5 cm and 10 cm.

\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h

\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10

\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm

3

.

Mass of the block is 2700 g.

Substitute the given values in \rho=\frac{m}{v}ρ=

v

m

to find density of a block.

\rho=\frac{2700}{1000}ρ=

1000

2700

\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm
